What to write in a Halloween card

Halloween cards are meant to be fun, so don't overthink them. Here's how to write one that raises a smile — whether it's for a trick-or-treating five-year-old or a friend who lives for the spooky season.

Quick answer

Happy Halloween to my favourite little monster! Have the spookiest, sweetest day ever.

Match the message to the person. A little one wants silly and sweet — friendly monsters, sweets, and a costume they can't wait to wear. An adult who loves Halloween wants wit: a pun, a knowing wink, a nod to the decorations they've had up since September.

Lean into the theme, then land one warm line. The spooky wordplay does the heavy lifting, but a single genuine wish — 'so glad it's your favourite time of year' — is what turns a throwaway greeting into a card they actually keep.

How to get it right

Pick a pun

Spooktacular, fang-tastic, creepin' it real — one good pun sets the tone instantly.

Name the fun

Costumes, sweets, carved pumpkins, scary films — one specific detail beats a generic 'happy Halloween'.

Keep kids sweet

For children, go silly and kind — friendly monsters and treats, nothing genuinely frightening.

End with warmth

Slip in one sincere line so the card lands as affection, not just a gag.

For kids

Boo! Hope your costume is brilliant and your bucket comes home full. Happy Halloween!
Wishing you a super-spooky Halloween full of treats, giggles, and just the right amount of scary.
Happy Halloween! Go and be the coolest one on the street. Save me a sweet?
Have a monster-mash of a Halloween! Trick-or-treat till your legs are tired and your bag is heavy.

Funny & punny

Happy Halloween! You're absolutely fang-tastic, and I'm not just saying that to be spooky.
Hope your Halloween is a real scream. Creepin' it real over here without you.
Wishing you a spooktacular day. Witch you a happy Halloween — see what I did there.
Eat, drink, and be scary. May your costume win and your sweets never run out.
Have a gourd time this Halloween. Sorry — I'll see myself out of the pumpkin patch.

For a friend or neighbour

Happy Halloween! So glad it's finally your favourite time of year — go all out, you've earned it.
Wishing you a wonderfully wicked Halloween. Save me a toffee apple and a good scary film.
Boo! Thinking of you this Halloween — hope it's full of fun, fright, and zero real horrors.
